This fabric replacement mirrors the same premium vinyl construction as the 110″ version, with added length to accommodate longer slide outs or configurations that require extra fabric. The 46″ width remains standard for compatibility with many RVs, and the option to cut to fit allows customization for a precise fit. The kit emphasizes affordable DIY replacement rather than professional service, offering significant savings for RV owners who prefer to manage maintenance themselves.
The product emphasizes UV resistance and waterproof performance, with a crack-resistant formulation designed to endure below-freezing temperatures. The color options—white and black—offer flexible styling that can blend with most RV exteriors.

This complete kit bundles roller assemblies, mounting brackets, rails, and the fabric itself, simplifying installation for many RV owners. The design focuses on protection against leaves, bird droppings, and water pooling at the top of the slide out, which can mitigate potential leaks. The included hardware and rails help ensure a secure, durable fit across a range of slide-out models, while the 0.075-inch thick alloy tube in the kit offers robust support in adverse conditions.
In terms of coverage, the kit targets standard 5th wheels, travel trailers, and motorhomes with a 6’3″ overall setup, paired with a 5’7″ fabric length.

Dulepax Slide Out Fabric Replacement (46″ x 200″)

The 200″ length option provides additional versatility for longer slide outs or for owners who prefer extra fabric to cover extended areas. Like the other Dulepax fabric options, this variant uses heavy-duty vinyl with UV resistance and waterproofing, plus crack resistance for cold weather. The white or black color choices support color coordination with most RV exteriors, and the fabric can be cut to fit multiple slide-out configurations.
The 46″ width remains a core compatibility factor across these replacements, ensuring a broad fit across many contemporary travel trailers and fifth wheels. The emphasis on DIY installation and cost savings is consistent across the product line, allowing RV owners to refresh their slide out aesthetics and protection without professional service.
SHADEPLUS RV Slide Out Topper Kit (Black, 8’9″)

The SHADEPLUS kit is presented as a complete package, including slide out top rollers, mounting brackets, hardware, rails, and fabric. This reduces the likelihood of missing components during installation and supports a straightforward upgrade process. The fabric is 18-ounce vinyl with UV and water resistance, produced with heat-welding techniques to prevent tearing in challenging conditions. The topper is designed to shield the slide out from debris while reducing water pooling and potential leaks at the top edge.
With an 8’9″ overall footprint and fabric length of 8’1″, this option fits a variety of mid-to-large slide outs on 5th wheels, travel trailers, and motorhomes. The black color offers a bold exterior look while prioritizing durability and long service life in harsh weather.
Buying Guide: Key Purchase Considerations And Comparisons
- Material quality: Look for heavy-duty vinyl (18oz or similar) with UV resistance and waterproofing. A crack-resistant formulation helps in cold climates.
- Fit and customization: Choose widths around 46″ with multiple length options to accommodate various slide-out dimensions. The ability to cut fabric to fit is a practical feature.
- Complete kits vs. fabric only: Full kits simplify installation with included rollers, brackets, rails, and hardware. Fabric-only options are best when replacing worn material while reusing existing hardware.
- Weather protection: Effective toppers reduce water pooling and protect the slide-out seal, potentially extending the life of the mechanism and the RV’s interior.
- Color and aesthetics: White and Black options provide versatility in matching exterior styling and visibility of dirt or stains.
- Installation: DIY replacements save money but assess your comfort level with mounting hardware and alignment. Some kits are designed for easier, tool-light installation.
- Durability overview: A robust alloy framework and reinforced welding practices contribute to a longer service life, particularly in high-wind or storm-prone regions.
- Maintenance: Regular inspection for fabric wear, seam integrity, and water drainage helps prevent leaks and damage to the slide-out mechanism.
- Warranty and support: Check product warranties and seller support, especially for aftermarket RV accessories that see frequent outdoor exposure.
- Use-case alignment: If your slide-out experiences heavy debris or frequent rain, prioritize models with superior water shedding and debris shedding designs.
In summary, the Dulepax and SHADEPLUS lines offer a balance of DIY ease, durable materials, and adaptable sizing for most 18 travel trailer with slide out configurations. When selecting, consider whether you need a fabric replacement or a full topper kit, and confirm the width and length options align with your specific slide-out dimensions. This approach ensures you achieve reliable protection, simplified maintenance, and a clean, protected travel experience.
